4 Claims. (Cl. 30-471) This invention relates to scrapers such" as areused by painters, carpenters, mechanics and penetrating deep intomoldings and crevices andother surfaces which are difficult to scrapeeffectively without specially designed tools;

To provide a tool of this kind that can be easily sharpened and willhave a practically unlimited life; Y

To provide an improved form of paint scraper that will simultaneouslyclean surfaces at an angle to each other, such as the edges ofclapboards and their flat faces, and which also may be used for scrapingnarrow and wide moldings and window frames, etc.

The invention is shown in the accompanying drawing in which:

Fig. 1 is a perspective view of a preferre embodiment;

Fig. 2 is a full end view of the embodiment of Fig. 1, showing the shapeof the scraper blade thereof;

Fig. 3 is a sectional view taken from the plane 33 of Fig. 2;

Fig. 4 is a sectional view taken from the plane 44 of Fig. 2;

Fig. 5 is a sectional view taken from the plane 55 of Fig. 2.

In the form shown in the drawing, the blade I comprises a fiat or planarplate of suitable metal, such as hardened steel, which is polysided,preferably pentagonal, with cutting edges formed by acute bevels 2 onthe side that faces away from the handle, so as to provide sharp edgeson all sides, which edges are all in the same plane, being the plane ofthe face of the plate I that lies on the side from which handle 3extends. This handle is made from bar stock in the form of a straightshank that is rigidly fastened to the plate I so as to extend atrightangles thereto and is bent upon itself at a point distant from theplate to form a hook-shaped grip portion 4 WhOSe portions 5 and 6 areapto the extended center line 1 of the shank 3 and converge toward eachother but are spaced apart to form a gap 8, which allows the workman tohang the handle from his pocket or belt. The hook-shaped or U-shapedgrip portion 4 being of greater transverse width than the diameter ofthe shank also gives the operator leverage control of the blade -to holdit to the work and to prevent the handle from turning in his hand. Therestricted space or gap 8 will grip the Workmans pocket or belt toprevent accidental displacement of the tool while allowing the mainportion of the grip to be of suitable transverse width to accommodate itto his hand.

The fastening of the shank 3 to the blade I is preferably accomplishedby threading the end of the shank at 9 to an abrupt shoulder I0 and thenmounting the blade between flat nuts ll and I2 mounted on the threadedend 9 and then peening the end l3 of the shank and grinding it flushwith the outer surface of the nut l2.

The scraper blade has a long edge IQ for scrapingwide surfaces and ateach end of this edge I4 is a narrow'edge' 15 disposed at rightangles tothe edge l4; and the edges l5 meet a pair of edges I6 which are inclinedat an acuteangle to each other and merge in a rounded point I! at theapex of this angle. The inclination of the bevel 2 with respect to theplane of the blade is preferably uniform throughout as is indicated inthe sectional views.

The scraper edges of the pentagonal form of blade are so arranged as toprovide right-angled corners l8 suitable for engaging surfaces meetingat right angles, either'at the right side or the left side of thehandle. In addition to having right-angled corners and a roundedacute-angled point H, the tool has obtuse angled points [9 at thejunction of the sides l5 and IS.

The shank of the handle 3 is attached to the blade at a point located inthe line of symmetry 20, Fig. 2, that bisects the line of side I4 andthe angle defined by the two inclined sides l6 and approximately at theintersection of this line of symmetry with a line connecting theobtuse-angled points I 9.

Although but one specific embodiment of this invention is herein shownand described, it is to be understood that details of the constructionshown may be altered or omitted without departing from the spirit of theinvention as defined in the following claims.

I claim:

1. A scraper comprising a flat planar blade proximately symmetricallydisposed with respect having a sharpened peripheral edge, and a handleshank in the form of a rod detachably connected at one end to anintermediate portion of the blade and extending at a right angletherefrom, and the opposite end of the rod being bent to U-form toprovide a handle grip of greater transverse width than the diameter ofthe rod and the legs of the U-formed grip lying on opposite sides of theaxis of symmetry of the shank.

2. A scraper comprising a blade having a polygonal peripheral edge,andahandle'shank in the form of a rod extending from an intermediateportion of the blade and at right angles thereto, and the other end ofthe rod being bent into U-form to provide a handle grip of greatertransverse width than the diameter of the rod.

and the legs of the U-formed grip lying, on opposite sides of the axisof symmetry of the shank, the legs of the U converging toward each otherbut being spaced apart at the open end of the. U.

3. A scraper tool comprising a thin steel 'blade' having front and rearplanar faces bounded by a peripheral edge, the edge being rendered sharpby a ground peripheral bevel on the front face,

, a perforation in the blade, a handle shank in the form of a roundrodthreaded on one end, a shoulder nut screwed on ,the shank, thethreaded shank end being projected through the perforation, a nut on thethreads forwardly 'ofthe blade and the blade being clamped between thenuts to rigidly attach it to the handle, the handle shank projectingrearwardly at right angles to the plane of the blade, the opposite endportion placement therefrom and the U legs lying on' opposite sides ofthe axis of symmetry of the shank, the said peripheral sharp edgecomprising a relatively long transverse top portion above the handlecontinuing into relatively short side portions at right angles theretoand at opposite sides of the handle, and said side portions continuinginto converging side portions extending to a point below the handle andthere the converging portions being joined by a convexly curvedportion,the handle at its point of attachment to the blade-being closer to therelatively long straight portion than to the curved portion.

4. A scraper tool comprising a thin steel blade having front and rearplanar faces bounded by a peripheral edge, the edge being rendered sharpby a ground peripheral bevel on the front face, a'perforation in theblade, a handle shank in the-form of a round rod threaded on one end, ashoulder nut screwed on the shank, the threaded shank'enwbeing projectedthrough the perforation, a nut on the threads forwardly of the blade andthe blade being clamped between the nuts to rigidly attach itto-thehandle, the handle shank projecting rearwardly at an angle to theplane of' theblade, the opposite end portion of the rod being bent intoU-form to provide a handle grip of substantial longitudinal andtransverse extent, and to provide also a hook for hookingly engaging theapparel belt of a user to transport the tool, one leg-of the U being theend portion of the round rod, and the U legs lying on opposite sides ofthe axis of symmetry of the. shank, the said peripheral sharp edgecomprising a relatively long transverse top portion above the handlecontinuing into relatively short side portions at right *angles theretoand at opposite sides of the handle, and said side portions continuinginto converging side portions extending to a point below the handle andthere the converging portions being joined by a convexly curved portion;
